Abstract (en)
[origin: EP0357012A2] Disclosed is a recording sheet feeding apparatus for feeding recording sheets singly to a copying machine, comprising a sheet storage cassette (B) for storing the recording sheets, a conveyance roller (1) for conveying the recording sheets from the sheet storage cassette (B) to a feeding roller (2), the feeding roller (2) for feeding the recording sheets conveyed from the sheet storage cassette (B) to the copying machine, a sheet separation roller (3), in contact with the feeding roller (2), for separating one of the recording sheets from other recording sheets so that the recording sheets are fed to the copying machine singly, and a rotation resister for resisting the rotation of the sheet separation roller (3) by frictional resistance of a resistant member in which the sheet separation roller (3) is further capable of rotating in an opposing direction to the feeding roller (2) by the resiliency of a spring (11) so that the other recording sheets separated by the sheet separation roller (3) are fed back towards the sheet storage cassette (B).
